Abstract
Abstract A method and apparatus for continuous part casting in which two moving continuous belts are provided each with a series of partial molds which are capable of alignment with the partial molds on the other belt to form complete part molds. The belts are engaged together, and the part molds defined, by the passage of the belts through idler wheels. Molten material is then poured into the part molds and allowed to cool. Passage of each belt over a separate idler wheel accomplishes belt separation and the removal of the parts.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
170 words
Apparatus for fabricating case parts from molds comprising: a first endless resilient belt having a matrix of first mold portions; a second resilient belt having a matrix of second mold portions, said matrix of second mold portions being complimentary to said matrix of said first mold portions to form a matrix of part molds when coupled together; means for continuously feeding molten material to said first endless belt, said first endless belt having passage defining means for introducing molten material into said molds; means for cooling said second mold portions, and means for heating said first mold portions until said molten material has solidified in said second mold portions, said means for feeding being adapted to supply molten material until said molten material has solidified in said second mold portions; means for driving said belts and positioning said belts to form said molds, whereby said feeding means, cooling means, and heating means are operatively connected to said completed molds; and means for separating said molds after solidification of said material.
